Metro Manila (CNN Philippines) — President Rodrigo Duterte and his family have billions of pesos in undeclared bank deposits, said one of Duterte's fiercest critics in government, Sen. Antonio Trillanes IV.

Trillanes, who ran for Vice President in 2016 and lost, said Thursday that a "concerned citizen" named Joseph De Mesa gave him documents allegedly proving that Duterte had over ₱2 billion in undeclared wealth in his bank accounts from 2006 to 2015.

[Translation: There is a businessman in Davao City who was a campaign contributor for President Duterte in the recent campaign. His name is Sammy Uy, who gave up to ₱120 million to various members of the Duterte family.]

Based on the documents, Davao City Mayor Sara Duterte has ₱121.1 million in her accounts, while Vice Mayor Paolo Duterte has ₱104.2 million.

The documents also showed that Duterte's common-law wife, Cielito "Honeylet" Avanceña, had ₱187.5 million in her accounts from July 2014 until March 2016.

Trillanes also said Duterte allegedly has other undeclared assets outside of his bank accounts.

[Translation: The money in these accounts is apparently his safety fund in case something happens to him. And that's only the money in the bank. He has more money placed everywhere, whether in real property, whether cash.]

Abella: 'Trillanes creating noise'

Speaking first to CNN Philippines, Presidential Spokesperson Ernesto Abella said the issue regarding Duterte's bank accounts has already been settled.

"Well, this is a rehash of something that he brought up about three days before elections and it's been properly addressed," he said. "He seems to be creating unnecessary noise. For whatever reason, we do not know. And I think we should leave it at that, unless he can come up with something truly serious."

Abella also said Trillanes should approach the relevant authorities instead of challenging the President directly.

"If he has any particular reason for raising these issues, then I think he should refer first to the authorities and leave the President to be doing more constructive things."

Abella said he will watch out for the other details that Trillanes said he would release Thursday at the Senate investigation on the alleged bribery scandal involving the Bureau of Immigration.

[Translation: We just ignoring him because if you call him on his taunt, he would really enjoy himself because he's in the limelight. However, the issue is fading away. There are so many new issues. Just leave him be.]

Crooks going free

Trillanes said he decided to release the documents to the public after seeing how the Duterte administration has been ignoring the fight against corruption, which has been one of the President's battle cries since being elected.

[Translation: This is very relevant so that the public can clearly see that we were fooled over the past months with the anti-drug war, where nothing has happened but the slaughtering of our countrymen. But during that time, nothing was done against corruption and, worse, the symbol of corruption, President Gloria Macapagal-Arroyo, was freed. And now, they want to let Janet Lim-Napoles free.]

Trillanes' statement comes a day after Solicitor General Jose Calida said the Regional Trial Court made an error in finding Napoles, a central figure in the alleged "pork barrel" scam, guilty of illegally detaining her aide Benhur Luy.

This is not the first time Trillanes has sought to challenge presidents in office. Trillanes, a former navy officer, was among the military men who staged a mutiny in a Makati hotel in 2003 to protest the alleged corruption in the Arroyo administration.

Arroyo, who won a seat as a Pampanga representative in the May 2016 elections, was freed by the Supreme Court last year after serving four years under hospital arrest for plunder charges.
